well in that case you need to check whether the service for wireless is started or not(in other words running or not ) and whether you are configuring it correctly or not

i did its all up and running, i figured out why it wasnt working at all though i had my modem set to PPPoA and my router doesnt support it so i hadt to set my modem to PPPoE.
now for some reason my wireless isnt working. every thing else works fine. i think my adapter on my computer is going out.
